My hackintosh have some problems install E5 4627 v2 CPU

[ayun2001]

my hackintosh is x79 platform, using E5 2650v2 and everything is ok! some days before, i found E5 4627 v2 is very cheap and power, so last night i install E5 4627v2 into my hackintosh. when i power on, ui become very slow, sometime ui switching like someone press pause button. but i changed my cpu to E5 2650v2, my hackintosh work is perfect(i do not change any config.plist).

who can tell me how to deal with this problem? thx...
